. @As RADIATOR.

Application filed January 14, 1926. Serial No, 81,238.

My invention relates to radiators, andfithas special reference toradiators in which.

heat is generated .by means of a gaseous fuel, and the heated gases arecaused to circulate through the radiators forheating portion of theelement broken away; and

thelsurrounding air by direct radiation.

In such radiators of this class as are provided with spaced radiatingloops therein, 1t

has hitherto notbeen found possible to ar-` range the heating/elementsthereof so that the ilamesfrom theburning gases and their npolychromatie effects Aupony and about the said elements are visible toobservers in a room, such as they fire `and glow exhibits of the commonopen fireplace. y l

The principal object of my invention is to provide a radiator ofthisclass Withheating elements and to arrange a transparent plate orfacing'in front of the elements so that, a person in the vicinity of theradia.

tor may watchy the pleasing elfects. of the burning gases in combinationwith the incandescent heating elements,n while at the Sametime he isenjoying the warmth from the radiator.

Another object of the inventionis" to arrange a transparent plate infront of Ithe heating elements in a radiator so as to pre-V venttheclothing of a person in close prox-` imity to the radiator from beingdrawny into the flame and from'being seton'flre' thereby. K e

A still further object `is yto `construct a radiator of this class withVa transparent plate of glass, or the like, preferablyV of aheat-resisting kind, for the heatingelements in the radiator insuchamanner that 'the plate can be easily attached to or detached fromthe radiator, and so that the liability to the breaking ofthe plate isminimized. -V

Other objects and advantages of my invention will be understood from thefollow-f which Figure 1 is a yrear elevation of a. live loop radiatorconstructed in accordance to my invention;

Fig. 2 is an endelevation thereof;

Fig. 3 is a vertical section taken along the line 3-3 of Fig. 2 andlooking toward the transparent plate, the heating elements beingremoved.

Fig. 4 is an enlarged central sectional view through one of theradiating loops;

"llllllllllllllllllwb,

Fig. 5 is a similar sectional view ofthe middle loop atv its top; l

Fig. 6 is an enlarged frontelevation of one of the heating elements;

Fig. 7 is aside elevation of Fig. 6 with a k tion with the other loopsexcept at the'top of the unit assembled radiator. The separate loops arejoined together by rods at the top and the bottom, as shown at 1 and 2.

At' the extreme top ythe individual loop sections open into each otherand form a chamber 3, which constitutesl a superheater, and also openinto each other below the superheater rand form a combustion chamber 4,which is separated from the superheater byV an angular wall 5.Otherwise, the

individual 'loop sections are separateor insulated from eachother andare preferably sealed at their joints by cement in the usual manner.

Near. the top of each loop section is a combustion passageway 6. Theseopen toward each 'other so as tol form a continuous passageway throughthe radiator, and at the ends of which the passageway is closed by walls7 and 8 in the outer loop sections. To

each of these walls is removably secured at l its lower end, the upperreduced part of av fire box 9 at respective end walls 10 and 11 of thebox'. .This reduced part vfits between a baiile wall 12, which is formedin all the `loop sections, and another wall 13, which is formed oppositeto the baille wall 12 and is integral with the angular wall 5 in four ofof the loop sections, as is shown in Fig. 4l,

but'is in the middle loop section 14 substi 100 -tuted by a wall15,'cor`responding in height with the height of the baffle wall 12, asis shown in Fig. 5.

The lire box is open at its top, and also at its bottom for the inlet ofair and is in its hold a heatradiating element `18 oflava 110 loopsection.

composition or other equivalent inaterial having incandescentproperties. At the bottoni of the fire box the back thereof has its edgeturned inward, Fig. 4, so as to forni a longitudinal flange 19 adaptedto rece-ive thereon a protecting element 2O which inay be ceinented tothe back, and which inay bev of a lire brick formation or solne otherheatresisting body. The fire box is at its bottoni front also providedwith an inward and upward lturned edge, so that thereby a longitudinalgroove 21 is forined which is adapted to receive therein the lower edgeof a transparent plate 22, which preferablyy is of a heat-resistingglass, such as that known by the tradenanie of pyrex, in order not to beliable to breakage from the heat of the burner. Under the reducedportion atv its top, the fire box is longitudinally provided with adownward flange 23, which with the front of the lire box forms an uppergroove 2et'adaptedl to 1' ceive therein the upper edge of' the glassplate. Both grooves 21 and 24 are of awi'dth sufficient to allow aclearance play of the plate therein, and the height of the plate ispreferably such that it allows the plate to be lifted up into the uppergroove 24 and to, clearthe upturned edge at the lower groove 21 when itis desired either to insert the plate into or to reniove it from thefire box, as is shown in Figs. 4 and 5. The front of the fire box isthus open, but normally closed by the plate, so that the Haines frointhe burner tips and their polychromatic effects upon the radiatingelenients 1S' niay be visible through the glass plate. Sufficient spaceis provided between the bottoni of the fire box and the series of loopsections for allowing the fire box to slide under the lower edges of thewalls 12, 13 vand 15 into place for connecting it and the burner tubewith the radiator R' or for disconnecting theni therefrom.

As has already been mentioned, the wall 15 of the middle loop unitextends upward about to the height of the bai'iie wall 1'2. This is forthe purpose of providing a direct opening to the flue 25' at the rear ofthe A damper 26 adapted to close this opening is mounted' on a rod,which is supported by the walls of the loop section 14 and extends totheoutside of the radiator, inay be operated by a bundle 27 at the endVofthe rod for causing direct suction through thefflueY at the initialoperation of the radiator, or for preventing such suction when theradiator is hot and functioning properly.

1n a foriner construction of a gas radiator, for which I was grantedLetters Patents, No. 1,470,293, in the United States on October 9th,1923, the gas burner was arranged in the upper part of the radiator. Forthe purpose of the present invention the gas burner is placed in thelower part of the radiator, as has already been described and as isclearly shown in Figs. 3 and Ll. 'Vith the exception of the constructionand the arrangement of the fire box with the glass plate and thefi'rebriclr therein, the burner tube, the heating elements thereon andi'ni'nor details in connection with the radiator, the constructiondisclosed in the present invention is similar to the one shown in theaforementioned patent, and the operation of both radators issubstantially identical. The operation of the radiator disclosed in thepresent invention will therefore be understood from the description inthe Letters' Patent referred to, so that a repeated description appearssuperfluous.`

Having thus described my invention, I claiin as new and desire to secureby Letters Patent of the Uni-tedv Stat-es the. following In. a gasradiator comprising separable gas-circulating loops secured together soas to forni longitudinally through the radiator a combustion passagewayclosed; by end walls, said loops opening into each other at the topthereby defining a superheater charinber, a lire box provided at itstopwith an open reduced portion fitting in this said longitudinalpassageway and withl its closed ends` detachably secured to said. endwalls, the fire boxV also havingv anV open front wall and. an openbottoni; the front wal-l having at the bottoni an inward and' upwardturned edge forming a longitudinal groove; a downward flange fornied atthe top of the fire box and under the reduced portion so that, thereby alongitudinal groove is formed at the front Iof the fire' box and abovethe firstinentioned groove; a gas burner mounted longitudinally in, thetire box and' near the bottoni thereof; and a. transparent plateslidably and removably niountedjv in said grooves and norinally closingsaid front wall.

In testimony whereof, I afiix iny signature.
